Abstract
A system control portion generates corrected image data by performing reduction processing of reducing input image data input into a display portion at a first reduction rate and image shifting processing of shifting positions of R image data and B image data of a specific color component included in reduced image data obtained by the reduction processing. The system control portion projects a corrected image based on the corrected image data to a screen by inputting the corrected image data into the display portion.
Claims5
A control device of a projection apparatus that projects an image from a display portion displaying the image to a projection object through an optical system, the control device comprising:
- a processor configured to
- generate corrected image data by performing correction processing including reduction processing of reducing input image data input into the display portion at a first reduction rate and image shifting processing of shifting a position of color image data of a specific color component included in reduced image data obtained by the reduction processing by a specific amount in a specific direction, the specific amount and the specific direction being predetermined according to the specific color;
- and
- project a corrected image based on the corrected image data to the projection object by inputting the corrected image data generated by the processor into the display portion,
- wherein when a region in which a pixel value is zero is present in an end part of the input image data, the processor controls the first reduction rate based on a size of the region.
A control method of a projection apparatus that projects an image from a display portion displaying the image to a projection object through an optical system, the control method comprising:
- a correction step of generating corrected image data by performing correction processing including reduction processing of reducing input image data input into the display portion at a first reduction rate and image shifting processing of shifting a position of color image data of a specific color component included in reduced image data obtained by the reduction processing by a specific amount in a specific direction, the specific amount and the specific direction being predetermined according to the specific color;
- and
- a projection control step of projecting a corrected image based on the corrected image data to the projection object by inputting the corrected image data generated in the correction step into the display portion,
- wherein in the correction step, when a region in which a pixel value is zero is present in an end part of the input image data, the first reduction rate is controlled based on a size of the region.
A non-transitory computer readable medium storing a control program of a projection apparatus that projects an image from a display portion displaying the image to a projection object through an optical system, the control program causing a computer to execute:
- a correction step of generating corrected image data by performing correction processing including reduction processing of reducing input image data input into the display portion at a first reduction rate and image shifting processing of shifting a position of color image data of a specific color component included in reduced image data obtained by the reduction processing by a specific amount in a specific direction, the specific amount and the specific direction being predetermined according to the specific color;
- and
- a projection control step of projecting a corrected image based on the corrected image data to the projection object by inputting the corrected image data generated in the correction step into the display portion,
- wherein in the correction step, when a region in which a pixel value is zero is present in an end part of the input image data, the first reduction rate is controlled based on a size of the region.
